INTERLOCKING METAL SH E ET-PILING.

Specification of Letters Patent.

Application am February 4, 1907. Serial No. 355,669.

"nols, have invented certain new and useful Improvements in InterlockingMetal Sheet- Piling; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilledin the art to which it appertains to make and use thesame.

This invention relates to a novel construction in interlocking metalsheet-piling, the object being to providesimple and eflicient pilingadapted more particularly for relatively light work, and consists in thefeatures of construction and combinations of parts hereinafterfullydescribed and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is aplan section of sheet-piling constructed in accordance with myinvention. Figs. 2 and 3 are similar views of modified forms ofconstruction.

My said piling comprises channel-bar units A and B, each provided onopposite sides of its web with flanges C D and E F, respectively, theflanges C and E being disposed on the side edges and the flanges D and Finwardly of said side edges and being oppositely disposed relatively tosaid flanges C and E. The flanges C and D of said unit A are provided attheir free ends with Outwardly-extending hooks G and H, in which thefree ends of the flanges F and E of adj acent units B are adapted, to bereceived and engaged, respectively. The edge flanges of both units wheninterlocked become oppositely disposed, and those portions of the web ofeach unit lying between the side edges and the inwardly-disposed flangeD and F lie in contact with each other. The said units are thus heldagainst relative movement in all direction except longitudinally and areparticularly firmly held against lateral movements in the direction ofprojection of the flanges thereof, there being a stepped joint besidesthe two hooked joints between the same to resist such lateral movement.

The member B herein shown and described coincides in shape with thechanne1- bar shown in Letters Patent No. 832,407, issued to me onOctober 2, 1906, in which two of said members coupled together form adouble unit, which is adapted to interlock with the said memberconstituting a sin le unit. By combining said unit B with the unit Aherein shown and in which the flanges are merely increased in depth andbent over at their free endsto form the hooks specified single-wallsheet-piling, which is very light and efl icient, may readily be formed.

I am aware that the use of units having hooked flanges is not entirelynovel; but I believe that such units in which all of the flanges areturned over to form hooks alternated with units have similarly-disposedPatented April 9,1907.

flanges, all of. which are plane, is novel, par

ticularly where the oppositely disposed flanges of each unit are oflsetrelatively to each other. Such relative offsetting of said flanges isvery effective for the reason that the stepped oint formed is far morewatertight, is better qualified to resist relative lateral movement ofsaid units in one direction, and also relieves the hooks and flanges ofa part of the strain to which they are apt to be subjected.

In the construction shown in Fig, 2 the units J are all of the sameshape, each being provided at and adjacent one side edge withoppositely-disposed plane flanges K and'L, respectively, and at andadjacent its other side edges with oppositely-disposed flanges M and N,respectively, provided at their free ends with hooks O and P, which areadapted to receive the free ends of said flanges K and L of the nextadjacent unit. This construction I consider most practicable for thereason that all units are of the same shape, and therefore only one setof rolls would be required to produce the same.

In the construction shown in Fig; 3 I have combined a unit B with a unitQ, conforming in construction to some eXtent'with the unit formingsubject of the patents to Vanderkloot, Nos. 763,526 and 786,329, saidunit Q having two plane edge flanges R extending in the same directionand two flanges S oppositely disposed to and offset inwardly relativelyto the flanges R, said flanges S being provided at their free ends withhooks T, adapted to receive the free ends of the flanges E of the unitB. The said flanges E of the latter are preferably short and relativelythick, their free ends being rounded. By forming a snug fit between saidflanges E and the recess receiving the same the units B and Q, will bevery firmly held against relative lateral movement in all directions.Relative pivotal movement in one direction will be least resisted; butowing to the thickness of the flanges E and the short radial distancebetween the fulcrum and the outermost corner of said unit such movementwill cause said units to bind, so that said flange E becomes so firmlyjammed in the recess receiving it as to necessitate bending of theflange R to cause said members to yield. This would require unusualstrain.

I claim as my invention- 1. Interlocking metal sheet-piling comprisingin combination a channel-bar member having a plane edgeflange, and aplane oppositely-disposed flange adjacent its edge, and a channel-barmember provided with an edge flange and an oppositelydisposed flangeinwardly of its edge, the free end of said last-named flangebeingprovided with a hook adapted to receive the free end of the edgeflange of the first-named member.

2. Interlocking metal sheet-piling comprising in combination, achannel-bar memher having a plane edge flange, and a planeoppositely-disposed flange adjacent its edge, and a channel-bar memberprovided with an edge flange and an oppositely-disposed flange inwardlyof its edge, the free ends of said last-named flanges being bent overoutwardly to form hooks adapted to engage the free ends of said flangesof the first-named member.

3. Interlocking metal sheet-piling comprising in combinationyachannel-bar unit provided with plane edge flanges, and with planeflanges oflset inwardly of its side edges and oppositely disposedrelatively to said first-named flanges, and a channel-bar unit havingsimilarly-disposed flanges having their free ends bent over outwardly toform hooks, the latter being adapted to receive the free ends of theoppositely-disposed flanges of said first-named unit.

In testimony whereof I have signed my name in presence of twosubscribing witnesses.
